SIG SAUER P320 XFIVE DH3 21-Round 9mm Pistol

The SIG SAUER P320 XFIVE DH3 9mm is a full-size Custom Works pistol configured around a 5-inch barrel, coyote finish, competition-oriented DH3 grip treatment, and three 21-round steel magazines. Developed as a purpose-built P320 variant, it combines the platform’s striker-fired operation with an optic-ready slide and a textured grip designed to provide a secure interface during sustained practice or competition. This listing is for manufacturer part number 320X5-9-DH3, UPC 798681665051.

DH3 Custom Works Configuration

The DH3 designation identifies a distinct factory configuration rather than a cosmetic variation of a standard P320. SIG SAUER specifies a coyote-colored full-size pistol with a DH3 silicon-carbide grip treatment. The added texture creates a more assertive gripping surface, helping the shooter maintain consistent hand placement when the pistol or hands become warm or damp. Because this texture is intentionally aggressive, buyers should consider how it will interact with their preferred holster, clothing, and carry method.

The grip and controls follow the modular P320 architecture, while the longer slide and 5-inch barrel give the pistol the sighting radius and front-end balance expected from an XFIVE-format handgun. It is a strong fit for range training, practical competition, and owners who prefer a larger pistol with a full firing grip. Fit remains personal, so handling a comparable full-size P320 before purchase can help confirm reach to the trigger and controls.

Five-Inch Barrel and Striker-Fired Action

This model uses a 5-inch 9mm barrel with a black finish. The striker-fired action provides the same basic operating system from shot to shot, while the full-size upper assembly gives the pistol a stable, deliberate feel. SIG’s exact catalog entry identifies the DH3 as a 9mm P320 with a 5-inch barrel and coyote configuration. The store’s protected specifications list no manual thumb safety, so safe handling depends on disciplined trigger-finger placement and a holster that fully covers the trigger guard.

Optic-Ready Slide and XRAY3 Sights

The Custom Works DH3 slide is optic ready, allowing the owner to install a compatible pistol optic after verifying the mounting footprint, plate requirements, screws, and torque specifications. An optic is not included with this SKU. Factory XRAY3 suppressor-height day/night sights provide an elevated conventional sighting system and remain useful if the owner chooses to run the pistol without an electronic sight. The slide’s serrations give the shooter defined surfaces for normal administrative handling.

Three 21-Round Steel Magazines

SIG SAUER specifies three 21-round steel magazines with part number 320X5-9-DH3. The three-magazine package is useful for structured range sessions or match preparation because it provides a working set without an immediate accessory purchase. Magazine-capacity restrictions vary significantly by jurisdiction, and this configuration may not be available in every state or locality. Buyers should confirm eligibility before ordering and use only magazines appropriate for the P320 platform.

Rail for Compatible Accessories

The full-size grip module includes an accessory rail for compatible lights or other lawful equipment. Confirm the accessory’s fit and ensure that any attached device is supported by the selected holster. Added equipment changes the pistol’s dimensions, balance, and handling, so function should be verified before the firearm is used for competition or defensive purposes.
